These genes are involved in various frailty-related outcomes, including different types of cancer (i.e., HDAC4, CASP9, NFE2L3, RILP, STK40, HAO2, SNX20, MRTO4, EMILIN3, P4HA3), cardiovascular disease (i.e., HDAC4, CASP9, SARS), diabetes mellitus (i.e., RPL36AL, SARS), and Alzheimer’s Disease (i.e., RPL36AL). The gene discussed is HAO2; the disease is Alzheimer disease.
